bifang's Introduction

BiFang BypassAV 小工具

自动化生成loader,实现加密、混淆、bypass沙箱、多种现有进程注入技术,动态编译生成。目的在于学习现有技术,实现易用的shellcode生成器,以及快速整合新技术到项目中。

使用说明

根据图形化界面选择生成即可,现支持net framework 4.0版本。

现有功能说明

不同方式自动上线

根据不同二进制文件;dns,http自动判断上线;http优先级高于DNS。

混淆

支持类名,方法,变量混淆;建议根据需求选择,全选可能报毒。

反沙箱检测

进程黑名单

存在以下进程认为是虚拟机,直接退出。

 "vmsrvc", "tcpview", "wireshark", "visual basic", "fiddler", "vmware", "vbox", "process explorer", "autoit", "vboxtray", "vmtools", "vmrawdsk", "vmusbmouse", "vmvss", "vmscsi", "vmxnet", "vmx_svga", "vmmemctl", "df5serv", "vboxservice", "vmhgfs", "vmtoolsd"

MAC地址检测

网卡MAC地址包括以下开头,直接退出。

"000569","000C29","001C14","005056","080027"

磁盘检测

磁盘大小小于50G,判定为虚拟机,直接退出。

启动启动时间检测

开机运行时间低于1h,判定为虚拟机,直接退出。

CPU核心数量与语言检测

CPU逻辑个数小于4个或者操作系统语言不是中文,判定为虚拟机,直接退出。

时间加速检测

运行时间存在加速,判定为虚拟机,直接退出。

bypass技术

  1. 进程镂空
  2. Dinvoke 调用API
  3. 载入第二个NTDLL绕过HOOK
  4. 映射注入
  5. syscall

后续功能

支撑net4.0以下版本。
